About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 778698001. Listed at 15 retailers as of November 3, 2026, with prices from HK$17,164 to HK$47,040, a HK$29,876 spread on the same certified stone. NZ Jewellers lists it at HK$47,040. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
